Types of Zeiss STERITAR B (813) for Contaflex Super BC

Here is another picture clearly showing the back of the last Steritar B (813) that I bought and that I cannot use in my Contaflex Super BC.

I just checked out your lens, and I got this on Google. I hope it helps. I'm not sure your Contaflex Super BC has the same mount as a Contaflex III. (link)

I have the Steritar B for my Contaflex super and it looks the same as the one you show.

It should mount in the same way as the other lenses. The 50mm is removed and the new lens is mounted. The red dot on the lens is lined up with the red dot on the lnes release tab on the camera and the lens rotated 1/4 turn to the right until it locks.

The dot on the Steritar can be hard to find. It is located on the outer chorome ring of the mount at (roughly) 4 o'clock.

I hope this is helpful.

I've been actively looking for a Steritar B for my Contaflex S for nearly 30 years. Good luck on your search. I believe that there were different bayonet mounts for the Tessar and the Novar(?) lens which was fitted to less expensive Contaflex's. That's probably what you've got.

Thanks for the info Bill. The lens for the cheaper contaflex was the Plantar, and I think that it had something to do with Eastern Germany, but not sure. Anyway, I knew the website I have been sugested here. It is info from 1958 when the Contaflex Super, Super BC and S did not exits. The Tessar lens was recalculated as from the Contaflex Super. I do not know if that has something to with this issue. The Steritar I have now seems the same as the one shown in the website for the Contaflex III and IV, when Zeiss changed of bayonet mount. I always though that the mount did not change with the recalculation of the Tessar. Still not much luck, but thanks for the help so far.

Meryl, thanks for your help too. I tried that but it did not work. How did you get your Steritar? Which model number is it? Is there any chrome or bronze in the mount? I noticed that the mount of the new Tessar lens has some bronze.

Hola Fernando, espero que hables espa�ol, te cuento que soy un coleccionista de Contaflex, tengo un steritar 813, que es el que estas manifestando con problemas, es normal que estos con el paso del tiempo tengan un corrimiento en la montura, me refieron a que el elemento trasero se desplaza hacia el interior y esto impide el correcto montaje. Para que tengas en cuenta este modelo va en los modelos que indica en el manual, entre estos tambien figuran Super, Super B y Super BC... el arreglo no es costoso pero si es preciso que lo realice alguien con esperiencia. NO permitas que te modifiquen la montura de la camara. Saludos Fernando

Hello Fernando. Yes, I do speak Spanish, which is my mother tongue. I am from Cadiz (Spain), but have been living abroad for the last 13 years. However, I will write you in English for the benefit of everybody if that is OK. Thanks a lot for the explanation about the problem, now I just need to find someone who can do the job. I recently came back to Brussels (Belgium) where it is impossible to fine a good repairer. before I lived in Scotland for three years. In Scotland and England there are a lot of repairers and they are very good, but Belgium is a dessert when it comes to film photography. I am coming back to Madrid (Spain) for Christmas, which is where my parents live now. Could you please reccomend me a good repairer in Spain (if possible in Madrid) who could do this work? If you do not know anyone in Madrid, I am happy to ship the lens to another Spanish town.

Hey guys dig this, Zeiss Ikon changed the contaflex f2.8 50mm Synchro Compur base lens some time between march 1963 and november 1965. What they did was changed the diameter just above the bayonet mount from 1.114" dia to 1.108" dia and renamed it the Synchro Compur X. some where between alpha serial D and F in the Super B series of cameras so being that the Super BC came later it is no wonder it does not fit. I found this out the hard way. About 2 years ago I posted some questions about steritars and got a very good response from member Meryl Arbing? (I hope I spelled that right) and she offered some places she had found her lens at and a couple others, I looked long and hard to find it, When I finally got it it did not fit because of what I mentioned above. Ok now check this out Listed in the original Contaflex Super catalog from 1959 (I believe around pg #18 it actually shows a "Near Steritar" for close up stereo pics .2-2.5 meter focal length, I also found one of these and it also does not fit. When I contacted Charles Barringer one of the authors of the Zeiss Compendium I explained what I found. He since has turned me over to one of his lens guru Zeiss buddies and we are currently trying to find out exactly when this change happened. So let's ask some questions Does anybody have a Steritar that fits a contaflex on a camera with the serial # starting after the letter D, I personally do not think this is possible and believe that when the company started having financial trouble they gave up manufacturing Steritars around this time. Trust me when I say that it is not you at fault here, have whoever is selling you the lens measure the diameter above the bayonet mount (should be 1.108"), If you find one please let me know. The lens guru's for the Zeiss Historical Society would love to hear about that one. Thanks Bobby May Bob_May_4@msn.com
